Serious malfunctioning
If malfunctioning occurs, stop using the unit
immediately and consult your local JVC dealer.
The camcorder is a microcomputer-controlled
device. External noise and interference (from a TV,
a radio, etc.) might prevent it from functioning
properly. In such cases, first disconnect its power
supply unit (battery pack, AC Adapter, etc.) and wait
a few minutes and then re-connect it and proceed
as usual from the beginning.
About moisture condensation . . .
● You have observed that pouring a cold liquid into a
glass will cause drops of water to form on the glass
outer surface. This same phenomenon occurs on the
head drum of a camcorder when it is moved from a
cool place to a warm place, after heating a cold room,
under extremely humid conditions or in a place directly
subjected to the cool air from an air conditioner.
● Moisture on the head drum can cause severe
damage to the video tape, and can lead to internal
damage to the camcorder itself.
For Your Maintenance
1) After Use
1. Turn off the camcorder.
2. Slide and hold OPEN/EJECT Q in the direction
of the arrow, then pull the cassette holder cover
open until it locks. The cassette holder opens
automatically. Remove the cassette.
3. Press “PUSH HERE” to close the cassette holder.
• Once the cassette holder is closed, it recedes
automatically. Wait until it recedes completely
before closing the cassette holder cover.
4. Tilt the viewfinder upward. Press BATT.
RELEASE p and remove the battery pack.
2) Cleaning The Camcorder
1. To clean the exterior, wipe gently with a soft cloth.
Put the cloth in diluted mild soap and wring it well
to wipe off heavy dirt. Then wipe again with a dry
cloth.
2. Open the LCD monitor. Wipe gently with a soft
cloth. Be careful not to damage the monitor.
Close the LCD monitor.
3. To clean the lens, blow it with a blower brush,
then wipe gently with lens cleaning paper.
NOTES:
● Avoid using strong cleaning agents such as benzine or
alcohol.
● Cleaning should be done only after the battery pack has
been removed or other power units have been
disconnected.
● Mould may form if the lens is left dirty.
● When using a cleaner or chemically treated cloth refer to
the cautions of each product.
4. To protect the unit, DO NOT . . .
... allow it to become wet.
... drop the unit or strike it against hard objects.
... subject it to shock or excessive vibration during
transportation.
... keep the lens directed at extremely bright objects
for long periods.
... expose the lens to direct sunlight.
... carry it by holding the LCD monitor or the
viewfinder.
... swing it excessively when using the shoulder strap
or the grip.
5. Dirty heads can cause the following problems:
• No picture during playback.
• Blocks of noise appear during playback.
• During recording or playback, the Head Clog
Warning indicator “ ” appears.
• Recording cannot be performed properly.
In such cases, use an optional cleaning cassette.
Insert it and play back. If the cassette is used more
than once consecutively, damage to the video heads
may result. After the camcorder plays back for about
20 seconds, it stops automatically. Also refer to the
cleaning cassette’s instructions.
If, after using the cleaning cassette, the problems
still exist, consult your nearest JVC dealer.
Mechanical moving parts used to move the video
heads and video tape tend to become dirty and worn
out over time. In order to maintain a clear picture at
all times, periodic check-ups are recommended after
using the unit for about 1,000 hours. For periodic
check-ups please consult your nearest JVC dealer.
How to handle a CD-ROM
• Take care not to soil or scratch the mirror surface
(opposite to the printed surface). Do not write anything
or put a sticker on either the front or back surface. If
the CD-ROM gets dirty, gently wipe it with a soft cloth
outward from the centre hole using a circular motion.
• Do not use conventional disc cleaners or cleaning
spray.
• Do not bend the CD-ROM or touch its mirror surface.
• Do not store your CD-ROM in a dusty, hot or humid
environment. Keep it away from direct sunlight.
